John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...

Like many in my profession, I have grown weary of the divisive and polarized debate over the science of climate change that has been such a disruptive force in recent years. This debate is too often carried out in extremes: Either you believe, or you don't. There appears to be no middle ground. And the uncertainty about whether climate change is caused by human activity or is an unavoidable ...

Clean tech in the United States has been on the rise in recent years— even through the recession and other challenges. Increasing wind power, falling solar costs, expanding electric vehicle markets, government stimulus and other investments have built a global clean tech sector that topped ...

Time and again the scientific urgency for global action on climate change is stifled by chaotic U.N. climate talks as politics and process prevents the world’s policy makers from coming up with a clear plan for 2020 to divide up the global effort of reducing greenhouse emissions. Looking ahead to the 2015 talks in Paris, can the U.N. Framework Convention on Climate ...

As things begin to heat up this summer, more and more HVAC facility managers and technicians will experience equipment and maintenance headaches. Take for example air conditioning systems. Even a well-maintained HVAC system consumes a lot of electricity, especially during the summer months. In ...

Situation: North American R&D facility of U.S.-based leading global security company builds prototypes of unmanned airborne systems for the purpose of testing and validation. Parts are produced in limited numbers throughout the fabricating shop. Component building process involves the use of adhesives that will only successfully bond within very specific temperature ...

When people look for the best kind of carpet washer, they often look for machines that can do a fast and effective job of cleaning. For commercial and industrial areas, efficiency in tackling tough cleaning tasks is an aspect that needs to be considered. Many people don’t really consider carpet drying times, since these units are simply used for cleaning. But a carpet cleaning machine plays ...

The – “Milser Mühle“ – has relied on AERZEN for 50 years When the Borgstedt Family took over the Milser Mühle 130 years ago, at first, it only produced feed material, and then, from 1918, it started to produce flour for human food. “Therefore we selected oilfree compressing AERZEN Positive Displacement Blowers of series GM as conveying air producer ...

Thousands of sparsely populated communities scatter in the remote areas of northern Canada. It is economically preferable to adopt the decentralized systems to treat the domestic wastewater because of the vast human inhabitant distribution and cold climatic conditions. Electro-technologies such as electrofiltration, elctrofloatation, electrocoagulation and electrokinetic separation have been ...

A new report released by the Global Commission on the Economy and the Climate identifies ten key economic opportunities that could close up to 96 percent of the gap between business-as-usual emissions and the level needed to limit dangerous climate change. The report calls for stronger cooperation between governments, businesses, investors, cities and communities to ...

Developed country governments have repeatedly committed to provide new and additional finance to help developing countries transition to low-carbon and climate-resilient growth. This assessment considers Japan’s efforts to provide “fast start finance” (FSF) between January 2010 and February 2012 in the context of the pledge by developed countries to mobilize USD 30 billion from ...

What began as an idea in a technology clean room has evolved into a globally-sought software platform system for the modern, environmentally-regulated marketplace. Actio Corp. was co-founded in 1996 by former college classmates — Russ McCann, a veteran high-tech entrepreneur from Silicon Valley, and Kal Kawar, a chemical engineer and industrial hygiene expert. McCann said the company was ...

Changing one’s ways or implementing new initiatives is difficult. It’s inconvenient. This seems especially true in the U.S. in recent years. Thus, the reluctance to implement smarter, cleaner strategies. Businesses in other nations have demonstrated that clean approaches – in operations and also in business strategies – have been successful in meeting the challenges of the ...

Thanksgiving is the one national holiday that has avoided being despoiled by excessive commercialization. It is a time when families and friends gather to appreciate one another and be thankful. But on the environmental front, we are constantly bombarded with stories of impending crises, environmental disasters, ecosystem collapse and species loss. Not only does this ...

In early November, about three weeks or what feels like 150 years ago, I ran into David Batker, the director of Earth Economics at the airport. I was on my way to the Soil Science Society meetings and he was going to Louisiana, where he is helping to put a dollar value on efforts to recreate the islands in the Mississippi delta as a ...

Stressing the importance of scientific integrity and transparency, EPA Administrator Lisa P. Jackson last month called for key changes to the process for reviewing National Ambient Air Quality Standards (NAAQS) to protect human health and the environment. 'It’s essential that the best science and the greatest transparency inform air quality standards that prevent illness and save lives,' said ...

Fracking is once again in trouble. Scientists have found that what gets pumped into hydrocarbon-rich rock as part of the hydraulic fracture technique to release gas and oil trapped in underground reservoirs may not be entirely healthy. Environmental engineer William Stringfellow and colleagues at Lawrence Berkeley National Laboratory and the University of the Pacific told ...

Nature provides all kinds of goods and services that offer economic opportunities, such as a water, food, building materials and recreation areas. However, this 'natural capital' is under pressure due to the growing world population and increased economic prosperity. Businesses, civic organisations and governments are therefore looking for sustainable ways to profit from natural capital, now and ...

It could be said that when the average man on the street hears about a new Environmental Fund or Climate Change Funds its easy to imaging the observer visualizing a member of Greenpeace flogging and IPO prospectus on Wall Street.
